mac address is learnt from different port channels.

Hello,

We are facing issue with mac address learnt from different port-channels,

1233267: Dec 27 11:28:44.833: %%MAC_MOVE-SW2_SP-4-NOTIF: Host XXXX.XXXX.XXXX in vlan 501 is flapping between port Po60 and port Po32

Connectivity is like 6500 as core running VSS and 4500 access switches are connected to Core and WLC is also connected to Core.

WLC to 6500 PO 60 , 4500 to 6500 PO 32.

Thanks in advance....

That's normally caused by a loop somewhere. Track down the MAC and start your troubleshooting from there. If it's a server make sure the NIC teaming is configure correctly. If so move towards the core, checking spanning tree along the way.

Hope it helps.
